If you want to compare to Windows: up till Windows XP it wasn't even possible to be logged in as multiple users at the same time, so the equivalent of a local root exploit was not really possible.
Incorrect on both counts.
Since at least windows NT server 4.0 you have had something called Terminal Server which gave remote users the ability to log on to your server and run applications (and with recent incarnations it is in a manner much faster than xwindows too). Windows NT 4.0 (regular) also had the ability to run programs as different users (through a bit of a trick), and this trick was turned into a real feature in Windows 2000 with the "run program as a different user" option. Windows XP was just the first one to allow a logged in user to keep all of his programs running while he is "logged out". I had a utility that I used to run on Windows NT 4.0 called "su" (and you can guess what that does) which allowed me to run any program as a different user.
And besides, being able to have multiple simultaneous logged in users has no relevance to the ability to have root exploits. As long as you have user privilege levels you can have root exploits.
You have a DRM technology that is OBVIOUSLY crackable (as all are), and a stupid industry that has just decided that they should use this technology, but hasn't yet implemented it in many places yet.
Do you:
A) crack it NOW and therefore allow the industry to quickly switch to a "better" scheme because it's not implemented yet
-or-
B) wait until it's in use everywhere and THEN crack it once it's too late for them to switch back?
What do you think would have happened if CSS was cracked after the first 2 DVDs were released? They would have changed the scheme really quickly.

And with the aforementioned system in place anyways, you've got a reasonably safe system. I'm sure that they have thought of several other safeguards as well.
And at $16 for.3 megapixels, this sounds like more of a novelty than a bargain, considering that 4-megapixel cameras are available now for less than a thousand dollars.
$1000 vs $16
I see a big bargain! Not everyone has deep pockets, not everyone can afford a digital camera. Some one wants to go on vacation for a week, snap up 3 dozen pictures (because they still take pictures like they would on film, not like us geeks who have had digital cameras for ages and take 100+ on any given night because, hey, it's free!), come back home and bam they have them all wonderfully on their computer, send them to all their friends, etc, etc, etc.
And I'm sure that the pixel range will increase with time, just give it a little to prove itself (or fail) as a buisiness model and then you'll see the bigger ones coming down too.
Oh wait, you can already rent digital cameras, and the big boys too, for not too expensive. One of my friends went on vacation for 10 days (I think he paid about $70), brought an old laptop and took well over 800 pictures at 3.1MP 1.2MB each. Damn. I'll just stick to my 2.1MP for now =(
So in other words, we're not going to be beaming power to Seatlle anytime soon.
Unless of course we opted to use something a little off the frequency of water, say 2.3GHz or 10GHz instead. It's a pretty wide spectrum...
But we ain't gonna be beaming power soon cuz it costs so damned much to lift if off the planet! =(... Not to mention that it'd take at least 5-10 years to build.
Actually I just remembered something else. Ironically the frequency that it used is not the resonance frequency of water (if it was it'd boil off the surface of your food and not cook the insides!). It's slightly off so that it will weakly be absorbed by the water molecules so it can penetrate the food and cook the insides as well. After about 2 inches of penetration the entire microwave will have been exhausted.
2.45GHz and 10GHz would be common wavelengths based on past studies. Your microwave operates at... oh 2.5GHz!
But fear not! There's more to the microwave science than meets the eye.
You see, in order for microwaves to do anything, they have to be absorbed into something and not re-emitted
This only happens when you have something in a liquid state... Otherwise, for example, when microwaves pass through steam they will excite the water molucules by causing them to vibrate madly, but as soon as the microwaves have finished passing through them the molecules stop vibrating, and nothing changes. The only way that you will get it to heat up a lot is if, in the process of causing those molecules to vibrate, those molecules rub against other molecules and transfer some kinetic energy. This can only happen effectively in liquid states.
If it's in a gaseous state and you have a constant beam that will continue to excite the water molecules in it's path, but due to winds and the fact that once you heat up a gas it will expand and move around on it's own you won't have a very large problem. If it's raining or you have a very dense cloud that's about to cause a storm, then you might have a problem, but under normal circumstances you'd be fine.
I remember reading somewhere that a good analogy was to think of them like this: imagine an object floating on water as waves pass by. The object will bob up and down but once the waves have passed there is no appreciable net change in energy to the object. However now imagine that this object was sitting right next to a fixed object, like a boat and a dock. As the boat bobs up and down it will rub up against the dock and friction will cause the dock to warm up. Same deal here.
Not to mention that the concentration of solar energy is 8x in orbit that of what it is on the surface of the planet, and it's a constant feed not disrupted by weather or atmospheric conditions...
According to an April 2000 article in the Electric Power Research Institute (EPRI) Journal, photovoltaic arrays in a geostationary Earth orbit (at an altitude of 22,300 miles) would receive, on average, eight times as much sunlight as they would on Earth's surface. Such arrays would be unaffected by cloud cover, atmospheric dust or by the Earth's day-night cycle.
So not only do you get sunlight all the time, but you can also beam this energy to low orbiting satellites, higher satellites, spacecraft, lunar bases or use it to propel spaceships and interplanetary probes. There's many a good reason to use microwave based power stations, but right now it's far too expensive (due to launch costs)... Once the launch costs come down this will become a real possibility.

Not very realistic, but a few surprises and intelligent responses. The parser also has problems, for example if I put "this, this, and that" it would seperate it into 2 lines "this, this" and "and that". However if I put "this, this and that" it would parse it fine.
Good cooling does not only allow overclocking. It also (and mainly) improves the life expectancy for the processor.
If you run your processor at 50% of the rated max as opposed to 35% of the rated max, how much more life are you going to get out of it anyways?
I have yet to have ANY processor (or hear of any) that have "burnt out", much less from overclocking.
And besides, in 5 years when the 15GHz machines are out, are you really going to need your 1.5GHz one? In 10 years when it finally does "burn out" and there are 50GHz machines out, who'll care?
I don't really see that as being of a concern =) In 1 year this processor will be long gone or doing something else anyways =)
did you notice a difference between the 900 p3, and the 1.5tbird?
Depends what I'm doing, but for most of my work not really. Yeah, it's a bit faster, so it'll load slashdot in, oh the same amount of time. IT'll boot up in 5 seconds less, it'll compile my files faster, that I do notice, yes, going +66% speed is noticable.
But you're not going to get anywhere near +66% speed out of using water to overclock than using air.
when amd starts manufacturing those tbirds at 3.5gz
Which they won't, because the TBird platform can't handle it (funny that everyone shoots down Intel when their platform can scale way past 10GHz, or 6 AMDMHz;> ), but when AMD does come out with that 3.5GHz machine it'll be aircooled.
Intel demonstrated an aircooled P4/3.0. You can always make bigger heatsinks and bigger fans. The old Beetle car and motorcycles are all aircooled, don't forget. They generate FAR more heat than your computer ever will.
Heat doesn't scale lineraly with MHz either. Future processors run with smaller transistors and lower voltages which decreases their heat emmissions.
There's all those distributed computing projects to choose from.
Ok, so let me rephrase.
Why is spending $80-$150 for the watercooled solution that will give you 100MHz more that you will spend helping other people get 8% more performance out of your computing for distributed computing which will result in a 1.0 * 10^(-12) percent completion of their data set so that you can get a silly performace counter a smidgem higher worth it? =)
Funny actually, I computed that at home it costs me $4CND/mo more to run distributed net than it does to not to (just from electricity). So why am I spending $4 to help someone else win $10000 for cracking something? =)
If I spend $250 for a DLT2000XT drive (which I did)
Cool! Where'd you get it! Cuz I would love to back up all of my data, but using a pile of CDRs isn't appealing.
Recurring vs. fixed costs.
Mind you, I bought 10 CDRWs and thus have 7GB to back up all of my important data on that I don't have to spend more money on. I still find that solution cheaper than yours, if a little less convenient. The nice thing with the CDRWs is that they can be read in anyone's computers.
It's the same attitude that leads gearheads to spend endless time & money souping up their cars. For a car enthusiast, getting an extra 10HP out of their engine is a big deal, even if it doesn't make any noticeable difference on the road.
Heheheh guilty as charged. Yes, I have gone to stupid lengths to increase the performance of my car, however I haven't really ever spent that much (well, headers and a custom exhaust set me back $1200 but it is actually quieter and you do notice the difference in accelleration), but so I can get to 60mph 0.5s faster than I could before. Whoopie! =)
Yeah, I'm just curious to know what non-coolness factors there are here.
But such extreme cooling measures might be necessary
Right, but do you remember the beetles? (as in the cars), they were aircooled. Motorcycles are aircooled. They generate FAR more heat than your computer ever will generate. Extreme example, yes, but just prooving that air can cool if you have sufficient amounts of it and big enough heatsinks.
As the article stated, you can easily make larger heatsinks and larger fans (and incidentally the larger the fan the less noise per CFM), and the Itaniums, they have insane power requirements (they need an 800W power supply!!) and yet they are quite effectively aircooled. And don't forget that as your transistor size decreases, so does your heat emissions. Imagine if they were to put a TEG (thermo-electric generator) on the CPUs to help them to power themselves! (sorry, funny idea)
I do not believe that anything other than aircooled will be required for a long time.
However, I find it likely that CPU designers in the future, will sacrifice some speed gains, in order to avoid costly coling systems, such as watercoolers.
Interesting point that I was kinda trying to make as well, we have computers that are far faster than most people need right now, so the push for faster and faster is kinda falling off. What do people need 1.4GHz for?
Actually some people think 0.1 GHz is worth about $400.
Show me a 1.2GHz user that will pay $400 to get his system to 1.3GHz.
Right, you won't find it. You did cite an extreme example, and very few people buy the top of the line processors, nevermind want to overclock them once they get them.
Noone has still answered the core of my question: what do you need 100 extra MHz for when you have a 1.4GHz processor? Or even a 900MHz processor?

.NET, haven't you heard of it. here is a link.. Exactly what you describe is half of it's purpose, despite what most people around here may think...
Excellent!! It's called
Didn't realize energy efficient cars were that close to reality!
JPEG (176 x 144 pixels)
80 pictures
1MB flash memory
So I can take 80 pictures that are 12.8KB each at 176x144 pixels... That's not even enough to be able to read the text off a picture that I took of a page from a book.
Doesn't seem very useful to me, I'd much rather drop the $200 on a ultrathin camera of some sort that gives me megapixel images.

it is 28, not 42.
Not very realistic, but a few surprises and intelligent responses. The parser also has problems, for example if I put "this, this, and that" it would seperate it into 2 lines "this, this" and "and that". However if I put "this, this and that" it would parse it fine.
Good cooling does not only allow overclocking. It also (and mainly) improves the life expectancy for the processor.
If you run your processor at 50% of the rated max as opposed to 35% of the rated max, how much more life are you going to get out of it anyways?
I have yet to have ANY processor (or hear of any) that have "burnt out", much less from overclocking.
And besides, in 5 years when the 15GHz machines are out, are you really going to need your 1.5GHz one? In 10 years when it finally does "burn out" and there are 50GHz machines out, who'll care?
I don't really see that as being of a concern =) In 1 year this processor will be long gone or doing something else anyways =)
did you notice a difference between the 900 p3, and the 1.5tbird?
;> ), but when AMD does come out with that 3.5GHz machine it'll be aircooled.
Depends what I'm doing, but for most of my work not really. Yeah, it's a bit faster, so it'll load slashdot in, oh the same amount of time. IT'll boot up in 5 seconds less, it'll compile my files faster, that I do notice, yes, going +66% speed is noticable.
But you're not going to get anywhere near +66% speed out of using water to overclock than using air.
when amd starts manufacturing those tbirds at 3.5gz
Which they won't, because the TBird platform can't handle it (funny that everyone shoots down Intel when their platform can scale way past 10GHz, or 6 AMDMHz
Intel demonstrated an aircooled P4/3.0. You can always make bigger heatsinks and bigger fans. The old Beetle car and motorcycles are all aircooled, don't forget. They generate FAR more heat than your computer ever will.
Heat doesn't scale lineraly with MHz either. Future processors run with smaller transistors and lower voltages which decreases their heat emmissions.
There's all those distributed computing projects to choose from.
Ok, so let me rephrase.
Why is spending $80-$150 for the watercooled solution that will give you 100MHz more that you will spend helping other people get 8% more performance out of your computing for distributed computing which will result in a 1.0 * 10^(-12) percent completion of their data set so that you can get a silly performace counter a smidgem higher worth it? =)
Funny actually, I computed that at home it costs me $4CND/mo more to run distributed net than it does to not to (just from electricity). So why am I spending $4 to help someone else win $10000 for cracking something? =)
If I spend $250 for a DLT2000XT drive (which I did)
Cool! Where'd you get it! Cuz I would love to back up all of my data, but using a pile of CDRs isn't appealing.
Recurring vs. fixed costs.
Mind you, I bought 10 CDRWs and thus have 7GB to back up all of my important data on that I don't have to spend more money on. I still find that solution cheaper than yours, if a little less convenient. The nice thing with the CDRWs is that they can be read in anyone's computers.
It's the same attitude that leads gearheads to spend endless time & money souping up their cars. For a car enthusiast, getting an extra 10HP out of their engine is a big deal, even if it doesn't make any noticeable difference on the road.
Heheheh guilty as charged. Yes, I have gone to stupid lengths to increase the performance of my car, however I haven't really ever spent that much (well, headers and a custom exhaust set me back $1200 but it is actually quieter and you do notice the difference in accelleration), but so I can get to 60mph 0.5s faster than I could before. Whoopie! =)
Yeah, I'm just curious to know what non-coolness factors there are here.
But such extreme cooling measures might be necessary
Right, but do you remember the beetles? (as in the cars), they were aircooled. Motorcycles are aircooled. They generate FAR more heat than your computer ever will generate. Extreme example, yes, but just prooving that air can cool if you have sufficient amounts of it and big enough heatsinks.
As the article stated, you can easily make larger heatsinks and larger fans (and incidentally the larger the fan the less noise per CFM), and the Itaniums, they have insane power requirements (they need an 800W power supply!!) and yet they are quite effectively aircooled. And don't forget that as your transistor size decreases, so does your heat emissions. Imagine if they were to put a TEG (thermo-electric generator) on the CPUs to help them to power themselves! (sorry, funny idea)
I do not believe that anything other than aircooled will be required for a long time.
However, I find it likely that CPU designers in the future, will sacrifice some speed gains, in order to avoid costly coling systems, such as watercoolers.
Interesting point that I was kinda trying to make as well, we have computers that are far faster than most people need right now, so the push for faster and faster is kinda falling off. What do people need 1.4GHz for?
Actually some people think 0.1 GHz is worth about $400.
Show me a 1.2GHz user that will pay $400 to get his system to 1.3GHz.
Right, you won't find it. You did cite an extreme example, and very few people buy the top of the line processors, nevermind want to overclock them once they get them.
Noone has still answered the core of my question: what do you need 100 extra MHz for when you have a 1.4GHz processor? Or even a 900MHz processor?
Yeap -- The server is a Precision 530 (not silent, but still very quiet) and the workstations are Optiplex GX150's and they are VERY quiet.
